Arguments: image-list
This function returns true if and only if the argument image-list is currently
open. Currently Common Graphics uses image-lists only for list-view controls,
which automatically open their image-lists when needed, so this
function is not likely to be needed by applications.
Note that if a list-view control that does not have the share-image-lists property turned on is removed from its dialog or the dialog is closed, then the operating system will destroy any image lists that were used by the list-view control. An application can call image-list-open-p to determine whether this has happened. On the other hand, close-image-list is not called when the OS destroys an image-list, and so an application cannot check for this occurrence by wrapping close-image-list, and should call image-list-open-p instead.
